Description

Technical Field

[0001] This utility model relates to the field of power plant stone and coal waste processing technology, specifically a rapid drying power plant stone and coal waste processing equipment. Background Technology

[0002] Coal ash is a low-calorific-value solid waste produced during the pulverization process of coal-fired power plants. It is mainly composed of non-combustible hard impurities such as gangue and rock. Its generation is an inevitable result of incomplete coal washing and the presence of impurities in the coal itself. For power plants, it is a negative product that requires costly treatment. Its main characteristics are high hardness, low calorific value, and high abrasiveness.

[0003] Existing waste materials are usually piled up in open areas. Rainy weather causes a lot of moisture to accumulate in the waste materials, which makes subsequent transportation or further processing very inconvenient. Therefore, drying treatment is necessary. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 5 This utility model provides a rapid drying power plant stone and coal waste processing equipment, including a machine body 1 and a feeding hopper 3 connected to the top of the machine body 1. Multiple inclined conveying plates 5 are rotatably connected inside the machine body 1. The number of conveying plates 5 is determined according to the internal size of the machine body 1, typically four, and arranged sequentially from bottom to top. The conveying plates 5 are connected to a drive mechanism for driving the conveying plates 5 to swing. The drive mechanism includes two motors 8, multiple driven wheels 16, multiple cranks 13, and multiple connecting rods 14. The motors 8 drive the driven wheels 16 to rotate. The two ends of the connecting rods 14 are connected to the cranks 13 and the driven wheels 16. The cranks 13 are connected to the conveying plates 5. A feeding rack 2 is connected to the bottom of the machine body 1, and the feeding rack 2 is connected to an air supply mechanism for supplying air to the machine body 1.

[0021] The four conveyor plates 5 are driven to swing synchronously by the drive mechanism, so that the waste material rolls down smoothly. In conjunction with the use of the air supply mechanism, the waste material can be dried and the drying efficiency can be improved.

[0022] A conveying device is connected to the bottom of the machine body 1. The conveying device includes a drive motor, two conveying rollers, a conveyor belt, and a feeding frame 2. The drive motor is connected to the feeding frame 2, and the power output end of the drive motor is connected to the conveying rollers. The conveying rollers are rotatably connected inside the feeding frame 2, and the two conveying rollers are connected by a conveyor belt. The dried waste material falls onto the conveyor belt and is then transferred to the next processing equipment.

[0023] The drive mechanism also includes multiple rotating shafts 9, multiple drive wheels 17, and multiple transmission belts 15. The rotating shafts 9 are rotatably connected to the machine body 1 and are used to drive the conveyor plate 5 to swing. The crank 13 is fixedly connected to the rotating shaft 9. The driven wheel 16 is connected to the drive wheel 17 via the transmission belt 15. The power output end of the motor 8 is connected to the drive wheel 17. Each motor 8 corresponds to one drive wheel 17 and two driven wheels 16. The motor 8 drives the drive wheel 17 to rotate, and the drive wheel 17 drives the two driven wheels 16 to rotate via the transmission belt 15. With the help of the connecting rod 14 and the crank 13, the rotating shaft 9 is rotated, which in turn drives the conveyor plate 5 to swing, allowing the waste material to roll down smoothly and improving the uniformity of waste drying.

[0024] The conveyor plate 5 is provided with multiple ventilation holes, and the end of the conveyor plate 5 is connected to the connecting seat 4. The rotating shaft 9 is connected to the connecting seat 4. The air supply mechanism delivers hot air into the machine body 1, and the gas moves from bottom to top and passes through the ventilation holes, which facilitates the drying and processing of waste materials.

[0025] Driven wheel 16 and drive wheel 17 are rotatably connected to body 1 to improve the stability of their rotation. A mounting frame 7 is connected to the back of body 1, with drive wheel 17 located inside the mounting frame 7, and motor 8 fixed to the mounting frame 7.

[0026] The two ends of the connecting rod 14 are connected to the crank 13 and the driven wheel 16 via shafts.

[0027] The air supply mechanism includes an air conveying pipe 10, a hot air blower 11, a base 12, and an air inlet channel 6. The base 12 is connected to the feeding rack 2. The hot air blower 11 is fixed to the top of the base 12, and the exhaust end of the hot air blower 11 is connected to the air conveying pipe 10. The air conveying pipe 10 is connected to the air inlet channel 6, which is open into the machine body 1. The hot air blower 11 delivers hot air into the machine body 1 through the air conveying pipe 10 and the air inlet channel 6. The hot air moves from bottom to top, facilitating the drying and processing of waste materials. Finally, the gas is discharged from the feed hopper 3.

[0028] The air intake channel 6 is inclined on the body 1. The end of the air intake channel 6 near the body 1 is at a low position, and the other end is at a high position, with an angle of 45° with the horizontal, which effectively prevents waste from entering the air intake channel 6.

[0029] The swing range of the conveyor plate 5 is Figure 5 In the case of A, 30° ≤ A ≤ 40°.

[0030] Working Principle: Waste material is fed into the machine body 1 from the feed hopper 3. The motor 8 then drives the drive wheel 17 to rotate. The drive wheel 17, through the transmission belt 15, drives two driven wheels 16 to rotate. Combined with the crank 13 and connecting rod 14, this drives the rotating shaft 9 to rotate, thus causing the conveyor plate 5 to swing. The waste material falls onto the conveyor plate 5 and rolls down smoothly as the plate swings. Simultaneously, the hot air blower 11 injects hot air into the machine body 1 through the air supply pipe 10 and air inlet channel 6. The gas flows from bottom to top, passing through the vents on the conveyor plate 5, ensuring uniform heating of the waste material, shortening the drying time, and improving processing efficiency. Finally, the gas is discharged from the feed hopper 3. After drying, the waste material falls onto the conveying device, which then transfers it to the next processing equipment.
